Description

The M.C. Enterprises 525003MC is a replacement sail switch for select Suburban furnaces. This air proving device acts as a safety component, preventing ignition until the furnace motor reaches 75% of its RPMs. It ensures proper air and gas mixture for smooth ignition by confirming the combustion wheel is rotating sufficiently.
